'M/A mv Kl/AZ Patented Jan. 8, 1963 3,071,951 KNITTED MESH FABRIC Milton Kurz, Cedarhurst, N .1. Filed Dec. 14, 1960, Ser. No. 75,820 11 Claims. (Cl. 66-495) As conducive to an understanding of the invention, it

is noted that unless knitted mesh fabrics, after stretching and finishing as by the appplication of resin thereto, do not distort, and retain their mesh design and formation, the fabric will be unattractive in appearance and hence unsaleable.

It is accordingly among the objects of the invention to provide a knitted mesh fabric having a unique stitch formation that may be made on a conventional knitting machine, which stitch formation will provide a fabric having a much greater degree of stabilization when treated in conventional manner as with a resin finish than similar fabrics made at the same cost of manufacture.

The fabricaccording to the invention is made on a machine having a minimum of two guide bars and one needle bar such as the conventional Kidde Knitter made by the needles when the threads on the other guide bar are engaged by the needles.

In the accompanying drawings in which is shown one of various possible embodiments of the several features of the invention FIG. 1 is a plan view of a portion of the knitted fabric prior to stretching, and

FIG. 2 is a view similar to FIG. 1 of the fabric after stretching. I

Referring now to the drawings, a plurality of pairs of threads a, b are used to make the fabric. One thread of each pair is always knitting and one thread of each pair is always laying in and not knitting.

In FIG. 1 the plurality of pairs is shown by the threads a b a [2 a b and the needle positions are shown by numerals 1, 2, 3, and 4, which form wales as is well known in the art. The beginning of each stitch is marked by lines and numbered IV (1 H 111 1V 1 it being apparent that four courses are used for each repeat.

In FIG. 1, stitch I is made by threads a a a knitting respectively on needles 2, 3, 4 and by the threads b b b laying in on the right side of needles 2, 3, 4 respectively.

In FIG. 1 stitch II is made by threads b b b knitting on needles 2, 3, 4 respectively and threads a a a laying in on the left side of needles 2, 3, 4, respectively.

In FIG. 1 stitch III is made by threads a a a knitting respectively on needles 1, 2, 3, and threads b b b laying in on the left side of needles 1, 2', 3 respectively.

It is important to note at this point the movement of the plurality of pairs of threads a, b 'between stitch II to stitch III In stitch II the threads a b a b a b are laying in and knitting respectively on needles 2, 3, 4. Then in stitch III the threads a b a b a b knit and lay in on needles 1, 2, 3 respectively. This movement of the plurality of pairs from needles 2, 3, 4, to needles 1, 2, 3, is necessary to develop the mesh fabric.

In FIG. 1 stitch 1V is made by the threads a a a knitting on needles 1, 2, 3, respectively, and the threads b b b laying in on the right of the needles 1, 2, 3, respectively.

In FIG. 1 stitch I is made by the threads a a a knitting on needles 2, 3, 4, respectively and threads b b b laying in on the right of needles 2, 3, 4, respectively. I

juncture of threads a b b Stitch I is a repeat of stitch I stated above but it is repeated-to show the complete cycle of this mesh fabric and to demonstrate a very important movement of the plurality of pairs between stitch 1V and stitch 1 In FIG. 1 at stitch 1V threads a a a are knitting respectively on needles 1, 2, 3, and threads b b b are laying in on the right side of needles 1, 2, 3, respectively: and in stitch I threads a a a are knitting on needles 2, 3, 4 respectively and threads a a a are laying in on the right side of needles 2, 3, 4. This movement completes the cycle to develop the mesh fabric.

At this point it must be noted that even though a plurality of pairs of threads have shifted to the left between stitch I1 and stitch H1 and the plurality of pairs of threads have shifted to the right between stitch IV and G, I, in lateral rows and the diamond meshes F, H, in

lateral rows: the lateral rows of meshes alternately being hexagonal and diamond shaped.

In FIG. 2 schematic hexagons and diamonds are drawn in more clearly to illustrate the different parts of the mesh.

The hexagons have vertices R, S, T, U, V, W and sides RS, ST, TU, UV, VW, WR, and the diamonds have vertices K, L, M, N, and sides KL, LM, MN, NK. The hexagon meshes are labeled G G G E E E J 1 J and diamond meshes are labeled F ,F F H H H Hexagon mesh G has its Vertex T formed by the juncture of threads a a and b at the beginning of stitch I This juncture is also the vertex of diamond meshes H at M and H at K and vertex of hexagon mesh J at W.

Vertex W of hexagon mesh G is formed by the juncture of. threads a 1 and I2 at the beginning of stitch I It is also the vertex of diamond meshes F at M and F at K: and hexagon mesh E at T. p

The side ST of hexagon mesh G is formed by threads b and a at the end of stitch III and through stitch 1V This also is the side MN of diamond mesh H The side SR of hexagon mesh G is formed by the This also forms the UV side of hexagon mesh G and also makes the vertices of diamond meshes H at. N and F at L. This occurs at stitch III through beginning of stitch IV The side RW of hexagon mesh G is formed by the threads a and b in stitch 11 This side is also the side LM of diamond mesh F The side WV of hexagon mesh G is formed by thread b forming an elongated loop in stitch 11 It is also side KL of diamond mesh F.

Side UV of hexagon mesh G is formed by threads a b [1 in stitch III through the beginning of stitch 1V It is also side SR of hexagonal mesh G the vertex N of diamond mesh H and the vertex L of diamond mesh F Side TU of hexagon mesh G is formed by threads a forming an elongated loop in stitch 1V This is also side KN of diamond mesh H The elongated loop formed on the back bar in stitch I1 and the elongated loop formed on the front bar in stitch 1V give the mesh fabric its stabilized characteristic.

Although the fabric of the type generally described having the desired characteristics could be made by any Front chain02 24 24 Back chain00 20 44 22 The following is a description of the parts of diamond mesh F Vertex L of diamond mesh F is formed by the uncture of threads b and a .at the beginning of stitch III Vertex N of diamond mesh F is formed by the juncture of a with itself at stitch IV.

Vertex K of diamond mesh F is formed by the juncture of threads a a and b at the beginning of stitch I It also is the vertex W of hexagon mesh G vertex T of hexagon mesh E and vertex M of diamond mesh F Vertex M of diamond F is formed by the juncture of threads a a and b at the beginning of stitch I It is also the vertex K of diamond mesh F and vertex W of hexagon mesh G and vertex T of hexagon mesh E The side LM of diamond mesh F is formed by the juncture of threads 11 and a in stitch I1 It is also the side RW of hexagon mesh G The side LK of diamond mesh F is made by the elongated loop of thread b at stitch 11 It is also the side WV of hexagon mesh G The side KN of diamond mesh F is made by the elongated loop of thread a in stitch IV. It also is the side TU of hexagon mesh E Side MN of diamond mesh F is formed by the juncture of threads a and b in stitch IV. It also is the side ST of hexagon mesh E The knitted mesh fabric above described which is made by a four course repeat resulting in rows of hexagonal and diamond shaped openings, is extremely stable and will not readily distort.
